Hey LDM, sorry about the slow response. I'll have your kit out today, I had several other late orders so I'm doing them together. I'm sure you will like my Hellcat interior kit, it really enhances the look of the Hellcat. Sorry, no P-40 in my future at this time! I tried looking through my plans to see if I could find the BT 1/8 Hellcat that I know I have, but I have too many plans. Maybe Hal can remember, but I think BT does show a scale aileron hinge on that set. But yes, it is the same size and scale as the CMP, in fact I was going to build the wing from the BT plans and use the CMP Hellcat fuselage, the BT wing will even fit in the CMP Hellcat wing saddle.
